A metro Atlanta polling site will remain open an additional 20 minutes Tuesday after a small electrical fire forced voters to evacuate, officials said.

DeKalb County fire Capt. Eric Jackson said firefighters responded to the fire just before 11:50 a.m. at the All Saints Catholic Church in the 2400 block of Mount Vernon Road in Dunwoody. Firefighters had the situation under control before noon, but the evacuation temporarily suspended voting at the church.

"We are going to have to extend hours at that polling place," Mary Frances with the DeKalb County Board of Registration and Elections said.

The fire was one of several issues voters found when they went to the polls. There were technical glitches in Gwinnett County; delays in the openings of two polling sites in that same county; and long lines in Fulton, Cobb and DeKalb.

Lines started forming early Tuesday as poll workers prepared for Election Day. Grady High School poll manager Melvin Davis Jr. set up machines just after 6 a.m.

That location brought out early riser Mike Plehal, who said he wanted to secure his spot in line. Cars filed into parking lots in Cobb, DeKalb and Gwinnett, and long lines formed before polls opened 7 a.m.

During the early voting period that ended Friday, there were few problems aside from isolated reports of voting machines 'flipping' voters' presidential choices, The Atlanta Journal-Constitution reported. A record 2.38 million people cast their ballots during the state's early voting period, which ended Friday.

Local officials plan to enact safety plans to make sure all goes smoothly Tuesday.

Deputies will be assigned to busier polling sites in Cobb County, and deputies plan to drive by polling spots in Gwinnett County, Channel 2 Action News reported.

Fulton County police didn’t assign special patrols, but police said officers will monitor polls.

We'll have election coverage all day with live updates here:

1:12 p.m.: One of the Express Poll devices at Christ United Methodist Church in Albany temporarily stopped working, according to The Albany Herald. The devices charge the yellow voting cards.

12:03 p.m.: Election Day gas prices dropped to the lowest level since 2004 in Georgia, according to AAA. The cost of regular gas is $2.23. In 2012, the cost was $3.28.

noon:  It's lunchtime and polling locations across metro Atlanta are reporting waves of voters trying to cast their ballots.  Fulton County spokeswoman April Majors said people who are working on Election Day usually head over to the polls during the lunchtime hour, so expect a rush.  "It can be pretty busy," she said.  Majors also warned voters that the Cliftondale Community Center, Roswell Library and North Fulton Service Center are usually hot spots.

11:21 a.m.: People are waiting in line at Life Church Smyrna Assembly of God. The line is moving quickly. Voters are spending no more than 20 minutes in line.

11:01 a.m.: Gwinnett County spokesman Joe Sorenson said voting machines were back online at the Bogan Park Community Recreation and Aquatic Center. They were down for a few minutes, he said.

10:35 a.m.: Gwinnett County spokesman Joe Sorenson said social media reports that an electricity problem led to down voting machines at Peachtree Elementary School are false. "That is incorrect," he said. However, he did report a "power problem" at the Bogan Park Community Recreation and Aquatic Center. Sorenson said the county was sending someone out to address the problem earlier Tuesday and he didn't know if voters could cast votes as of 10:35 a.m.

10:29 a.m.: "I'm pleased to say all the polls opened on time and on schedule," Fulton elections director Richard Barron told The AJC. "We're expecting 70 percent turnout." The previous early voting record in 2012 was 152,562. When absentee ballots come in, Barron said he expects the early vote will be about 284,000. "It's a major accomplishment for us," he said. "Early voting worked in our favor. We're pleased that our residents listened. Our hope is that today's voters also will be patient if they have a wait." Barron also addressed reports of inoperable voting machines at Therrell High in southwest Atlanta. "There seems to be a rumor that isn't true," he said. "The poll manager had to reset express polls two different times. They've already processed more than 300 voters today. Right now, she's processing voters. She's processing voters as fast as she can. We don't want to see anybody leave because of equipment malfunction. We do encourage them to go back. We probably received the fewest emails and complaints since I've been here. I'm not going to do any premature celebrating just because the first three hours have gone smoothly, but I am happy."

10:25 a.m.: The Winnona Park precinct in the City of Decatur is reliably Democratic and that has been on display this morning with the number of women showing up to vote in pantsuits, the adopted emblem of Hillary Clinton supporters. A preteen girl, spotting a voter leaving the voting site in a pantsuit, yelled out, "Yes! Pantsuit!"

9:41 a.m.: Reports of inoperable voting machines at Therrell High School are false, Fulton County spokeswoman April Majors said. "We don't understand how that rumor has spread," she told The AJC. She added machines have been working properly and more than 200 people have voted.

9:30 a.m.: Mansfield, Ga., Mayor Jefferson Riley posted this on his Facebook page: "Remember the voting days: Republicans vote on Tuesday, 11/8 and Democrats vote on Wednesday, 11/9."

Ferguson Elementary School opened 8 minutes late due a problem with equipment, which has now been fixed. Sweetwater Middle School opened 12 minutes late due to a problem unlocking the polling units. "The biggest issue today so far has been people showing up at Elections HQ in Lawrenceville trying to vote," he said. "This location is only a polling place during early voting. People can deliver their absentee ballots to elections headquarters in Lawrenceville, but all other voting must be done at a voter's regular polling place."

8:35 a.m.: Voting is heavy and slow in eastern Cobb County this morning, with wait times of about an hour at Hightower Trail Middle School.
